When the U-shaped bracketsare in raised position, they wlll support a box 5 thereon until they aretilted by a longitudinal move ment of the hon in the direction of travelor" the conveyors, which is in the direction of the arrow a, Figure 3.

in paomno standsat present constructed, it

is necessary for the packer to lift the filled boxes and deposit thesame onthe conveyor, and this is a laborious operation. Inthe presentdevice device there is no lifting of the boxes.

The packing stand proper comprises a base l4 which is supported oncasters ii of conventional structure, so the stand can be moved towardsand away from the conveyor side. Extending upwardly from the base 14 areuprights i6 connected together by a cross bar l1. Rotatably mounted inbearings l8 in the upper end of the uprights 18 are axially alined armcarrying shafts l9, which extend towards each other and are rotatablymounted in a sleeve 20, which has ing the device to boxes of differentlengths.

Secured to the outer ends of the shafts l9, which rotate in unison, arebox supporting arms 24, which incline slightly upwardly; and on whichthe box rests during a packing operation, andv the stand is away fromthe side of the conveyor,

thereby allowing any other boxes moving on the conveyor to be conveyedand during which action the conveyed boxeswill engage the variousbrackets at the various packing stations, and swing the same downwardlyuntil the box passes the bracket and at which time it will move tovertical position under the influence of its spring.

Rotatably mounted in bearings carried by the uprights I6 is ahorizontalshaft 25, which is' provided with latching discs 26. One side of thelatching disc is provided with a recess 21, and the latching arm 2|extends downwardly and inwardly and terminates in a nose 28, which rideson the periphery of the disc 26 for holding the arms 24 in raisedpositiorras shown in Figure 4. When the stand is pushed towards theconveyor and the arms 24 are over the conveyor, a trip arm 29 carried byshaft 25 is rocked in the direc-.

tion of the arrow b, Figure 4, and disc-261s rotated to a point wherethe latch arm nose 28 will enterthe notch 21, thereby allowing the boxsupporting arms 24 to move downwardly, and the box to be deposited onthe hinged brackets 8, and at which time the stand is withdrawn from theconveyor to move the arms 24 from an overlyingrlation to the conveyorand then the packerimparts a longitudinal push on the filled box. Thisaction will tilt the brackets 8 and deposit thebox' on ,the conveyorchains. The above action is repeated as each box is filled and placed onthe conveyor.

It will be noted that as the stand is pushed towards the conveyor, triparm 29 engages the side of the conveyor for the tripping operation. Triparm 29 is provided with stop arm 30, which limits the pivotal action ofthe trip arm and maintains the same in position. If desired a spring 8|may be provided for positivelyreturning the trip arm to normal positionfor resetting the arms 24, as it is obvious the operator, before puttingthe empty box on the arms 24 could raise the arms 24 slightly and spring8l would rotate disc 26 to its proper position so the latching nose 28would engage the periphery thereof, and notch 21 would be in positionfor the next unloading operation.

From the above itwill be seen. that a fruit and vegetable packer's standis provided, which sary for the packer to lift boxes as they are filled,

and deposited on the conveyor.

The invention having been set forth what is claimed as new and usefulis:

1. The combination with a conveyor having tiltable receptacle supportingmeans for supporting a receptacle above the conveyor until tilted, of, atruck movable towards and away from one side of the conveyor, said truckhaving receptacle supporting arms at an elevation above the tiltablereceptacle supporting means on the conveyor, latching means carried bythe truck and cooperating with the arms for maintaining said armselevated above the tiltable receptacle supporting means and latchreleasing means carried by the truck and positioned to engage the sideof the conveyor when the truck is moved towards the conveyor when thereceptacle is supported above the tiltable receptacle supporting meanson the conveyor.

2. A conveyor loading truck for loading a conveyor from the sidethereof, said truck comprising a movable frame movable towards and awayfrom the side of the conveyor, said frame having pivoted receptaclesupporting arms at its upper end above the conveyor, latching meanscarried by the frame and cooperating with the arms for maintaining thesame elevated above the conveyor and latch, control means carried by theframe and positioned to engage the side of the conveyor for releasingthe latch control means of the arm when the truck reaches its limit ofmovement towards the conveyor and the receptacle supporting arms aredisposed above the conveyor.

3. A receptacle supporting truck adapted to be moved towards the side ofa conveyor for depositing receptacles on the conveyor, said truck comprising a frame, a rock shaft in the upper end of said frame, receptaclesupporting arms carried by said rock shaft and adapted to supportreceptacles at an elevation above the top of the conveyor and toextendacross the top of the conveyor when the truck is moved towards the sideof the conveyor, latching means for maintaining said receptaclesupporting arm in raised position and latch releasing means carried bythe truck and positioned to engage the sidepf the conveyor as the truckreaches the limit of its movement towards the conveyor forallowing thereceptacle supporting arms to move downwardly for depositing areceptacle on the conveyor.

4. A device as set forth in claim 3 wherein the latching means comprisesa rockable shaft carried by the truck, notched arms rigidly mounted onsaid shaft, latching arms carried by the receptacle supporting arm shaftand engaging the cams, said latching arms having members .slidablyengaging the cam surfaces of the cams and receivable within the notchesthereof upon release of the latching means.

5. A device as set forth in claim 3 wherein the rock shaft in the upperend of the frame is formed from axially alined sections each of whichcarries a receptacle supporting arm, a sleeve mounted on said axiallyalined sections and bayonet connections between the shaft sections andthe sleeve, whereby the receptacle support- 70 ing arms may be adjustedin relation to each other.
